Thank you very much, very informative and educational.Vanja #66 wrote: ↑22 Dec 2023, 10:34Unfortunately, there is not a lot that we know for certain, neither about sidepod-diffuser rear corner interference nor the floor flow structures in these complex RB-like floors. As for rear corner and diffuser flow management, what Ferrari had in 2022 was working very well obviously, but in 23 the floor edge got higher and they made their launch sidepods without a big side wall surface and much more tapered, which left a lot more of the floor exposed. In my view, downwash sidepods are working better with 23 rules because they somehow prevent the dirty air (and crosswinds) from entering diffuser better than 23 launch inwash design from Ferrari.

Do they make this revolution I do not know cause I am not an aero guy and I am relaying on your expertise.
Also if you have time and will would be good to make some analysis/explanations on that subject to present here cause it is important for the 2024 car.
I would be very grateful and would be happy to read it.
Thank You.

I believe the mechanism at play there is literally having a wall that generates slight pressurisation in yaw in that area which is forcing the dirty air probably up and towards rear tyre. The thing about this is that very small changes in pressure in this area can have big consequences for the path the low-energy dirty air will take. If you only look at flow-vis, you might get a wrong impression that all the air in this space is always going towards diffuser mouse hole, but in reality we don't know what is happening 20mm from the bodywork surface, much less 50 or 100mm which is very important for understanding what is really going on.

So how all this will translate to Ferrari 24 car, I have no clue I really wouldn't be surprised if they go full-width downwash ramp. Nor if they keep their hybrid solution slightly changed... The front will be very RB-like for sure, that much is certain, I think they should skip right to the final RB19 inlet and undercut design, no need to go step-by-step with the new car.
Considering how bad SF-23 was in some corners compared to F1-75 even in the final spec and especially early in the season, it's valid for Ferrari staff to point this out. It's not a big statement, I think they just pointed it out to quantify they see a definitive progress with the new car in an area that was a weak point.
I want to mention about the AR car when I saw for the first time that pic with flow-wiz of the car I was amazed how huge inwash the car have, which was completely unpredictable from visual inspection of the body work, at least to me as F1 fan.
